Enum TryFromError 

pub enum TryFromError {
    UnsupportedSourceShape {
        src_shape: &'static Shape,
        expected: &'static [&'static Shape],
    },
    UnsupportedSourceType,
    Generic(String),
}

Error returned when try_from fails to convert a value.

Variants

UnsupportedSourceShape

The source shape is not supported for conversion.

Fields

src_shape: &'static Shape

The shape of the source value.

expected: &'static [&'static Shape]

The expected shapes that would be supported.

UnsupportedSourceType

The source type is not supported (simpler variant without detailed shape info). The source shape information is available in the enclosing error context.

Generic(String)

A generic error message.

Trait Implementations

impl Clone for TryFromError

fn clone(&self) -> TryFromError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TryFromError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TryFromError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TryFromError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
